'FOUNTAIN-PEN.

SPECIFICATION forming-part of Letters Patent No. 758,934, dated May 3,1904.

Application led January 15, 1903. Renewed March 23, 1904. Serial No.199,627. (No model.)

To rtZ Mmm t ntfty concern.

Be it known that I, JOHN SorER PURDY, of Brooklyn, in the county ofKings, and in the State of New York, have invented a certain new anduseful Improvement in Fountain- Pens; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying' drawings, in which- Figure l is alongitudinal sectional view of a penpembodying Vmy invention. Fig. 2 isa view showing in elevation the pen illustrated in Fig. 1. Fig. 3 is atransverse sectional view through the body of the pen looking' towardthe pen-point. Fig. 4 is a longitudinal sectional view through thepoint-section and parts attached thereto, and Fig. 5 is a longitudinalsectional view of ,the air-tube and cleaner.

The object of my invention has been to provide a fountain-pen whichshall have, among others, the following advantages: of insuring a steadyand uniform flow of ink, of being capable of using a soft and elasticpen-point, of preventing' the formation of air-bubbles, of insuring theproper admission of air into the pen-body, and of having its partsreadily separated for the purpose of cleaning; and to such ends myinvention consists in the fountain-pen hereinafter specified.

In carrying my invention into practice I' provide a pen-body A, intowhich a ring B is screwed, the engagement being preferably by aright-hand thread. The ring B is provided with an internal thread b,which is preferably of an opposite character from that of the thread bywhich the ring engages the body and in the instance chosen forillustration is a left-hand thread. The thread b preferably terminatesat the base of a shoulder b, and a point-section C is screwed into thering B by engagement withthe thread and preferably until the rear o1'upper end of the point-section comes in contact with the shoulder L'.The point-section is provided with a pen-slit c for the reception of thepen-point D. An ink-passage c is formed in the lower portion of thepoint-section and extends from a flaring' opening' cz 1n its rear orupper end forward and opens beneath the pen-point.

Above the pen a passage 03 isformed through the pen-section, and a tubeE, preferably of metal, is inserted in the passage c". The said tube hasits forward end preferably flattened and bent down toward and close tothe upper surface of the pen-point, where it is provided with a slit efor the admission of air. A rod F is mounted in the tube E and at itslower or forward end is bent upward and extends through a slot e in thetube E, the upwardlybent end of the said rod serving as a handle f, bywhich the rod can be moved in the tube. The rear end of the said rod isprovided with an eye j, which eye is engaged by an eye g, formed upon arod Gr, the latter being' preferably formed of wire and of sinuous shapeand extending' through the passage 0; The length of the rod F ispreferably such thatits handlef' can reach to the forward or lower endof the slot e in the tube E, so that the eye'upon the upper or rear endof the rod will not contact with the adjacent end of the tube E andprevent movement of the rod until the said rod has reached the forwardend of the slot e. The rods F and G constitute cleaners. A sleeve H issecured, preferably, upon the pen-section C, as by a threadedengagement, and such sleeve is provided with a reduced portion /L forthe reception of the cap I. lf desired, the ring B can at its forward orlower end be provided with a flaring opening for the reception of aconical shoulder 0*, formed upon the pen-section, and the sleeve can bescrewed against said shoulder. The rear or upper end of the body ispreferablyprovided with a central socket a, in which is held, preferablyby friction, a tube K, the tube being readily removable from its socketfor the purpose of cleaning. The tube extends forward toward the forwardend of the body, and at such end theY tube is open. The tube is alsopreferably provided with a metal sleeve for protection and with openingsf through the tube and the sleeve. A rod L is loosely mounted in thetube K and at its forward or lower end is provided with an enlargementor shoulder which, as illustrated, consists of cross-arms I, thatprevent the said rod from entering the said tube beyond a givendistance. Ifv desired, the said cross-arms can be omitted.

IOO

In the operation of my fountain-pen the holder is filled with ink andthe pen operated by the mere act of Writing. The air Will pass up thetube E and into Vthe body of the holder and Will cause a free flow ofink down the passage beneath the pen-point. The act of tipping the peninto Writing position will cause the rod L to fall and break any bubbleswhich may have formed in the lower end of the chamber in they pen. Thepresence of the Wire G in the passage c prevents a too ready flow ofink. Should the How of ink be obstructed either by the clogging of thetube E or the passage c', the end of the rod F is engaged in anyconvenient manner-such, for instance, as by a hole z' in the cap I-Whenthe rod F and the Wire G are caused to' reciprocate in their respectivetubes by moving the handle f back and forth in the slot e. By themovement of the said handle the pen is conveniently and immediatelyrelieved from any clogging and a proper flow of ink is immediatelyproduced. Should any ink travel down the tube E, it is conducted by suchtube to a point above the pen-point, Where it Hows upon the pen-pointand passes Without difficulty to the paper Which is being Written upon.The eye f', at the rear end of the rod F, forming, in effect, ashoulder, by coming in contact With the pen-section C prevents anystrain being communicated to the tube E, such as would cause said tubeto be drawn out of its place in the pen-section. Since the air isperfectly supplied to the pen by means of the tube E, the iow of ink tothe pen-point does not depend upon the point being raised from thepassage c' beneath it, and I am consequently enabled to use a pen havingelastic nibs and one Whicliwrites more easily than the pens required byall-the fountain-pens of which I am aware. The tube K being merelyforced into its socket can, like'all the other parts of my pen, bereadily removed for cleaning.

It is obvious that various changes can be made in the above-illustratedconstruction Which Will be Within the scope of my invention.

Having thus described my invention, what I claim isl. In a fountain-pen,the combination of a pen-body, a tube extending longitudinally of.

the chamber in said pen-body and being readily removable therefrom, anda rod loosely mounted in said tube and adapted to fall back and forththerein.

2. In a fountain-pen, the combination of a pen-body, such body having atapering socket a tube'eXtending longitudinally of the chamber in suchbody, said tube being engaged solely by friction with the said taperingsocket in said body, and a rod loosely mounted in said tube.

3. In a fountain-pen, the combination with a pen-body, a tubeextendinglongitudinally of the chamber in said body, and a rod looselymounted in said tube, said rod being adapted to fall from said tube, andto break air-bubbles formed in said chamber.

4. In a fountain-pen, the combination of a pen-body, a tube extendinglongitudinally of the chamber in said body, and a rod loosely mounted insaid tube, said rod having a shoulder to prevent saidrod from completelyentering said tube.

5. In a fountain-pen, the combination of a pen -section having anink-passage beneath the pen-point, and having an air-passage above thepen-point, said airfpassage having an opening upon its sideoppositetosaid penpoint.

6. In a fountain-pen, the combination of a pen-section having anink-passage beneath the pen-point, and a; tube inserted in saidpensection above the pen-point, said tube having an air-receivingopening upon its side opposite to said pen-point. p l

7. In a fountain-pen, the combination of a pen-section having anink-passage beneath the pen-point, and a tube inserted in saidpen-section above the pen-point, said tube having an air-receivingopening upon its side opposite to said pen-point, and having an openingadjacent to the upper surface of the pen-point.

8. In a fountain-pen, the combination of a pen-section having anair-admitting passage therein, a rod mounted in said passage yandextending outside the pen-holder, so as to be capable of operation whilethe parts of the penholder are assembled.

9. In a fountain-pen, the combination of a pen-section having anair-admitting tube therein, and a rod mounted in said tube, and having ahandle extending through a slot in said tube.

10. In a fountain-pen, the combination of a pen-section, anair-admitting tube mounted in said section, a rod extending through saidtube. and having a handle extending through a slot in said tube, saidrod havinga shoulder adapted to engage with the pen-section to preventthe Withdrawal of said tube.

ICO

1l. In a fountain-pen, the combination of a I pen-section havingpassages above and beneath the pen, cleaners mounted in said passagesand connected together, one of said cleaners having means for engagementthat is accessible when the parts of the pen are assembled.

In testimony that I claim the foregoing I have hereunto set my hand.
